Welcum to Pixies dzbuster........And great question!

In my humble opinion....as a seamstress....(whatever that has to do with anything) I would say....get as erect as you can be......measure from the tip of the helmut to the base of the shaft just before it meets the scrotum. This is prolly standard though I know of some men who measure 6" from the floor whether there is anything there to measure or not! (Teehee db! JK hun!) Oh....and also measure around the shaft for thickness....(this counts on the test as extra credit!)...........When you have done this post the results, along with a pic, in the men's forum and the ladies here at Pixies will be glad to let you know if you did it correctly! LOL!
